字符串传递给execSync有新的行，我想执行字符串作为一个单一的命令

Question

我想传递node.js的execSync函数一个不在一行中的字符串(我的意思是它有许多新行)。例如:

require('child_process').execSync(`echo hello 
world 
to
all > /home/kali/Desktop/output`);

但是我有以下错误:

/bin/sh: 2: world: not found
node:child_process:903
throw err;
^
Error: Command failed: echo hello 
world > /home/kali/Desktop/output
/bin/sh: 2: world: not found

114, 108, 100,  58,  32, 110, 111,
116,  32, 102, 111, 117, 110, 100,

]
],

116,  32, 102, 111, 117, 110, 100,
10
]
}

是因为有新行。它不会执行"echo hello world to all "/home/kali/Desktop/output"作为一个命令。但是它会执行"echo hello"， "world"， "to"one_answers"all"命令，所以我有错误。由于我的项目的一些限制，我不能使用双引号和引号内反引号。我该怎么办?

编辑:

new line是execSync的分隔符。是否有办法改变在execSync的分隔符?或者是否有任何替代execSync，其分隔符不是新行?

您应该能够使用replace

来删除换行符。

require('child_process').execSync(`echo hello 
world 
to
all > /home/kali/Desktop/output`.replace(/(rn|n|r)/gm, ``));

相当于运行

require('child_process').execSync(`echo hello world to all > /home/kali/Desktop/output`);
